PFERD conveniently lists all Tungsten Carbide Burs and and Bimetal Hole Saws and Accessories into a single and concise catalog, Section 202.
PFERD hole saws are manufactured with welded high-speed cutting edge teeth for long service life, high concentricity and high cutting speed. The bi-metal construction prevents breakage of the hole saw at high loads. Highly-finished weld seams result in clean and precise holes, and easy handling. The knock-out slots allow rapid and easy removal of the cores.
Hole saws are used in drill presses, lathes and milling cutters as well as in hand-held power drills.
Their high concentricity ensures reliable tool control. PFERD hole saws cut perfectly round holes quickly and easily, whether in unalloyed or alloyed (stainless) steels, castings, aluminum, copper, bronze, brass, wood, plastics or similar materials.
Maximum Cutting Depth for all Sizes: 1-3/8”.
PFERD hole saws come with an alternating 4/6” tooth pitch (i.e., alternately 4 and 6 teeth per inch, counted on the circumference) which helps prevent chatter.
Bi-metal hole saws range in height from 1-3/8“ to 2-1/4“, depending on type.
Common workpiece materials include Unalloyed steel, Castings, Bronze, Plastics, Wood and Wallboard |
